iOS Question Using picker in iOS

[Luiz Fernando Orlandini]

Hi All,

I have a layout with some input informations. One of them is a Picker.

Something like below...

Picker
Text
Text
Button

All the fields have 5 points between of free space.

What is the problem? Picker show all the options just after the layout is showed. This is one point. How can I not show all options until the user click in it?

The second problem. I can access the text field immediately after the picker, cause the my options block them. Is it possible the change these behaviour?

Thanks.

I think that you should switch to a button with ActionSheet (see DBUtils example). It will work as you want.

I didn't understand the second problem. Sorry.

Erel, I will se the example.

The second problem...

When i put a picker in the view all fields bellow become inaccessible, cause picker overlaps the text filed immediately below it. Is it more clear now?

Erel, I see DBUtils example, and is not the case to implement an Action Sheet with a button.

In Android I have implement a Combo Box, but in iOS we don't have a combo, just a picker.

You can use Picker. Picker is a large view so you need to make room for it. It is not possible to hide the items.

Why not? This is a kind of limitation of B4i, cause in native development, all options just appear, when you get the component focused.

This is how the native Picker works. It is a wheel with values. The values always appear. Maybe you seen an app that fills the items when you click on it.
